Circular Component Pattern issue in Inventor 2022

[spencerpatterson]

I recently upgraded from Inventor 2019 to Inventor 2022 and noticed that adjusting the component pattern with the mouse looks a bit stiff. In this example video I attached, I made a circular pattern of diamonds around the y-axis. I have Element 1 to be constrained with the xy plane and xz plane, and want to expand and shrink the pattern with my mouse. When I move Element 1 of the circular pattern to the sides, the other Elements follow Element 1 in the same direction instead of expanding the distance from the center axis. Only when I release the mouse button will the other Elements snap back into place. This used to work properly on the 2019 version. Why does the 2022 version do this instead? It just really throws me off when working freehand because I work with some assemblies where the components need to have some axis of freedom.

EDIT: I provided a better example to show that this is not exactly hardware related. For context, the 4 red nodes you see in the beginning are all constrained to be equally distanced apart around the y axis, like a circular pattern is *supposed* to do. But when I start moving the yellow node pattern, it gets very janky and merges into itself. Then I put a purple pattern in there where the first purple node is is completely flush with the red node. It's a little janky but the purple nodes quickly correct themselves to follow the motion the red nodes. I have no clue what is going on here or why you would need to set up a constrained pattern like the red nodes to control a circular pattern. The circular pattern takes like 3 steps to get what you want whereas I had to make a one-by-one constrained pattern to produce the result I was looking for. Waste of time!

Just out of curiosity, are you running 2022.3 update?

[spencerpatterson]

Yes.

Hi Spencer,

The behavior does seem odd. But, I guess it could be related to how the components are constrained and what is used to create the circular pattern. If possible, please share the files here. I would like to take a look to understand the behavior better. There could be a bug to fix.

Many thanks!

Hi Johnson,

It's been a while since I had a response so I found the example assembly I used. This file has all three types of patterns unsuppressed.

I want to remind the readers that the red diamond pattern is just 4 nodes manually constrained together to *look* like a circular pattern, while the yellow and purple nodes are circular patterned. Just mainly focus on moving the red diamonds with your mouse versus the yellow pattern; the purple pattern is the only circular pattern that works as intended, but the "driving" purple node is constrained to the "driving" red node in order for it to work.

I look forward to your solution, thanks!

Hi Spencer,

The files seem to be created using unreleased internal build. Did you created using the build on Inventor Feedback Community? If yes, please continue the discussion there since it is bounded by NDA.

Please share a dataset saved on a released build.

Many thanks!

Hi Johnson,

This was not made using any unreleased build. I simply made these diamonds using my company's part/assembly templates from 2019 and they saved as 2022 files. Attached, I tested another diamond pattern again, but using 2022's default part and assembly options in the home menu; this is completely from scratch this time. There are no custom iproperties or presets. The result is still the same.

Please verify if this screenshot is a stable build I'm using.

EDIT: I reuploaded the New Diamond Test because I forgot to save.

Hi Spencer,

Many thanks for sharing the files! The behavior does look strange. I cannot explain it. There seems to be subtle change in terms of how the constraints are solved. The movement of the yellow pieces does not make sense to me. I need to work with the project team to understand it better. It has been reported as INVGEN-62541.

Thanks again!
